Paper Abstract

The non-uniform response of the sensors are increasingly prominent with infrared focal plane arrays (IRFPAs) being more and more used in infrared measuring systems, which gives uncorrected images and measurement error. The merits and faults of several non-uniformity correction algorithms attracting broad attention in recent years, including two-point correction, multipoint correction, temporal high pass filter correction (THPFC), artificial neural network correction (ANNC), were analyzed and discussed in this paper. In addition, the algorithm validation has been respectively carried out on these methods, using existing infrared images sequences and the possibility of application of scene-based non-uniformity correction techniques for infrared measuring systems, is discussed by preliminary research and exploration.
